Couple things...you don't give the length so I am not sure what the limbs measure but I am sure
that , like randman says, it ain't bending for the length of the working limb as it should. Lot of
work going on coming out of the fades and that is probably where the tick is coming from.
Again you did not specify but if the bow is red oak it is most likely letting go from the inside out.
And... not trying to offend but the sheetrock tape makes your bow unsuitable for the "Bows"
forum. Only natural materials are allowed. I did the deed myself once upon a time and it got
moved as I am sure yours will be. Ain't no big deal.
You should probably remove the tape if you decide to do a hic backing. Use a heat gun and a scraper
or putty knife. But if it is red oak, personally, I would not mess with trying to save it.But that's me.
